CV1099 / VR99 / 6K8G * triode hexode

Size This valve measures 110x40mm overall and has an octal base. See also the second example in a different envelope.

* The CEI valve is marked both CV1099 and 6K8G, but the EVS datasheets show that 6K8G is CV1944 and do not list it specifically as a prototoype for CV1099.
